Unknown Unknown - Not Provided
Authentication Bypass in KAYSUS KS-WR3600 Router Firmware Allows Privilege Escalation

Publication date: 2026-01-08

Last updated on: 2026-02-02

Assigner: MITRE

Description
KAYSUS KS-WR3600 routers with firmware 1.0.5.9.1 allow authentication bypass during session validation. If any user is logged in, endpoints such as /cgi-bin/system-tool accept unauthenticated requests with empty or invalid session values. This design flaw lets attackers piggyback on another user's active session to retrieve sensitive configuration data or execute privileged actions without authentication.

Can you explain this vulnerability to me?

This vulnerability affects KAYSUS KS-WR3600 routers with firmware 1.0.5.9.1, allowing an authentication bypass during session validation. If any user is logged in, certain endpoints like /cgi-bin/system-tool accept unauthenticated requests even with empty or invalid session values. This flaw enables attackers to piggyback on another user's active session to access sensitive configuration data or perform privileged actions without needing to authenticate.


How can this vulnerability impact me? :

The vulnerability can allow attackers to gain unauthorized access to sensitive router configuration data and execute privileged actions without authentication. This can lead to compromise of network security, unauthorized changes to device settings, potential disruption of network services, and exposure of sensitive information.
